Lanxess has acquired biocide manufacturer Verichem based in Neville Township near Pittsburgh.

The purchase significantly bolsters the German specialty chemicals company’s portfolio of biocides, its position in the U.S. material protection market and its global biocide manufacturing network. Both parties have agreed not to disclose financial details.

With the addition of Verichem’s approximately 20 employees, Lanxess will employ more than 300 people in the region, including those at the company’s North American Headquarters in Findlay Township and its manufacturing facility in Burgettstown. Lanxess will gain access to the privately owned Verichem’s complementary portfolio of biocides, as well as active ingredients registered with the U.S. Environmental Protection Agency (EPA).

They are used to protect coatings, adhesives, construction materials, as well as pulp and paper. The biocides prevent the deterioration and discoloring of materials caused by microorganisms.

The transaction will close with immediate effect. Verichem, which recorded sales of roughly $10 million in 2010, will be integrated into the Lanxess business unit Material Protection Products (MPP).
